Subject: remove possible-textrels from powerpc asm
X-Git-Tag: v1.1.9~46
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=cf1a9d9d16a79322df15b344a2617b79ebb12705;p=oweals%2Fmusl.git

remove possible-textrels from powerpc asm

these are perfectly fine with ld-time symbol binding, but otherwise
result in textrels. they cannot be replaced with @PLT jump targets
because the PLT thunks require a GOT register to be setup, so use a
hidden alias instead.
